What is the prime factorization of 60

2*2*3*5

Step-by-step explanation:

We need to factor 60 until it is prime numbers

60 = 12*5           5 is prime 12 is not

     =3*4   *5       3,5 prime   4 is not

    = 3 *2*2 *5     2,3,5 are prime

Rearranging the order

    =2*2*3*5

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
